Twilight - This page provides a way for you to obtain a table of the times of
local astronomical twilight for the current year. Astronomical twilight is
the time when the center of the sun is between 12° and 18° below the
horizon. From the end of astronomical twilight in the evening to the
beginning of astronomical twilight in the morning, the sky (away from urban
light pollution) is dark enough for all astronomical observations.
